Problems solved by technology

Although this invention can measure the liquid level at the liquid outlet, the structure of the liquid outlet is complicated due to the liquid level detection mechanism installed at the liquid outlet. The structure at the mouth is more complex, the assembly is complicated, professionals are needed, and the cost is increased. At the same time, the accuracy of liquid level detection is not high, and the detection of low liquid level is not sensitive enough, and false alarms or delayed alarms are prone to occur, which brings customers great inconvenience
[0005] In addition, most of the connections of the existing detergent additive container are non-removable structures, and it is impossible to take out the detergent additive container for rehydration when the liquid level is low
Even if some washing additive containers can be taken out, the structure is complicated and it is difficult for ordinary users to operate

Embodiment 1

[0034] Such as Figure 1-2 As shown, in this embodiment, a device for automatically dispensing detergent additives includes a container 1 for holding detergent additives and an installation part 2 for carrying the container 1. The container 1 is set in the installation part 2 in a removable manner. It includes at least one set of liquid level detection structures for detecting the liquid level inside the container 1 .

[0035] In the above solution, because the container 1 is generally connected with various pipelines, it is difficult to take out the container 1 for liquid replenishment and other operations, requiring professional maintenance personnel to operate, which causes great inconvenience for users to replenish detergent additives. The container 1 of the present invention is set in the installation part 2 in a removable manner, so that it is convenient to take out the container 1 for liquid replenishment maintenance and other operations. Because the automatic detergen...

Embodiment 2

[0041] This embodiment serves as a further limitation to Embodiment 1. In this embodiment, the liquid level detection structure further includes a fixed part 9, and the detection part 6 is sealed and wrapped in the fixed part 9, and both ends protrude from the fixed part 9. It is provided that one end of the detection part 6 is detachably sealed and inserted into the container through the fixing part 9 , preferably, the fixing part 9 is connected with the container 1 through threads.

[0042] In the above solution, the fixing part 9 may be made of insulating material, and the fixing part 9 inserts the detecting part 6 into the container. The fixing part 9 itself is not inserted, and the function of the fixing part 9 is to seal and fix the detection part 6 at this time, making it easier to seal and connect with the container 1 .

Embodiment 3

[0044] This embodiment serves as a further limitation to Embodiment 2. In this embodiment, one end of the detection part 6 is detachably sealed from the bottom of the container 1 through the fixing part 9 and inserted into the container. The fixing part 9 is made of insulating material. The fixing part 9 is at least partially inserted into the container, and the height from the top of the inserted part to the bottom of the container is the lowest measurable liquid level.

[0045] In the above scheme, the detection part 6 of the liquid level detection structure according to the present invention is inserted into the container from the bottom of the container 1, which is more convenient for detecting whether the washing additive in the container is sufficient, and at the same time, because the liquid outlet 5 is also arranged at the bottom, it is arranged at the bottom of the container. The bottom is easy to install, and no other structures are added, which saves costs. In this ...

Abstract

The invention discloses an automatic feeding device for washing additives and a washing machine. The device comprises a container for containing the washing additives and a mounting part for carryingthe container, wherein the container is arranged in the mounting part and capable of being picked and placed; the device also comprises at least one group of liquid level detection structures for detecting the liquid level in the container. The container is placed in the mounting part and capable of being picked and placed, so that the additives can be supplemented conveniently, and when the container is placed back in the mounting part, the at least one group of liquid level detection structure can continue to detect the liquid level sensitively and accurately.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a washing additive automatic feeding device and a washing machine. Background technique [0002] With the development of science and technology, more and more washing machine automatic delivery technology is applied to the working process of washing machine. The automatic dosing technology can automatically and accurately add the detergent dose according to the amount of clothes, which can largely avoid the artificial dosing of detergent, which leads to inaccurate detergent dosing; on the other hand, the detergent automatic dosing technology can Putting in a large amount of detergent, it can be used for a long time once it is put in, which greatly saves the time and cost of adding detergent for each laundry. However, because of the automatic dosing technology, when there is not much detergent left, especially when there is not enough detergent additive dose for one-time dosing, t...
